What should a new HP Tuners user know before tuning their first vehicle?
- Credits and licensing: a license is tied to the vehicle's VIN, controller serial number and operating system. Most engine computers take about 2 credits; after that you can reflash it as often as you like (HP Academy, HP Tuners). Purchased credits appear after Help > Resync Interface in VCM Editor.
- Read and save the stock file first — reading comes before licensing.
- Hardware you'll want: a wideband. Narrowband sensors can't calibrate the whole range.
- Order of work: injector data first, then drivability (idle, cruise, part throttle), WOT last.
- Logging: VCM Scanner handles logging; PCM of NC recommends 15–20 minute logs covering every operating state.
Confidence: medium — sources disagree or are limited; check the sources below.
